I love this idea! And what if your child could design their own things to go in the house and have these 3D printed - both encouraging creativity, inventiveness and introducing these great technologies of laser cutting and 3D printing. The reason I picked up on this is that the haptic (3D virtual touch ) 3D modelling software we have developed at Anarkik3D is so easy to learn and use that with guidance about what is 3D printable, anybody can get into doing and making!
